The AirTAC GFR600C25LC2T AirTAC Filter Regulator 1 in NPT Low-Pressure is a genuine G-series filter regulator: water separation, 40 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has See datasheet ports, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The GFR600C25LC2T is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single size-600 body. This configuration is built for a 1 in NPT port, is the low-pressure regulator type, carries the standard 40 um filter element, drains condensate by differential pressure, and is fitted with a round pressure gauge scaled in psi. The aluminium alloy bowl suits the larger size-600 flow path, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and options that include automatic or manual drains, a 5 um element (code W), square or round gauges with MPa, psi or bar scales, and G or NPT threads in place of the PT standard. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for your application.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). Air must not freeze in the unit. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

Field order is size, port, drain, type, bracket, gauge, shape, scale, grade, thread, reflux — a blank position takes the default. Example: GFR300-08 is a 300 body, PT1/4", differential drain, standard type, bracket included, gauge fitted, 40 µm, PT thread, no reflux valve.
A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom. The GFR600 uses an aluminium-alloy bowl; the 200, 300 and 400 bodies use PC.

Feeds large-bore clamping and hold-down cylinders on a metalforming press from a single 1 in supply point, giving the circuit filtered air and a regulated setting suited to low-pressure clamping work.
Serves as the air-prep point for case packers, wrap-around labellers and palletiser sections, where the 1 in NPT port carries the whole section supply and the 40 um element protects downstream valves and cylinders.
Mounted at the main drop feeding a machining cell, it removes condensate and swarf-carrying particles before tool changers, clamps and air jets, with the psi-scaled gauge giving operators a direct pressure readout.
Choose the size and port against the air demand of the circuit: size 600 with its 1 in NPT port is the largest step in the GFR range, so it suits lines with the highest consumption. This unit is the low-pressure regulator type - the right pick where the process works at reduced settings rather than full line pressure; we can confirm the exact adjustment band from the datasheet. Drain is differential-pressure as standard, with automatic (A) and manual (M) versions available if your duty needs them. The element here is the 40 um standard grade - specify W for the 5 um option where finer filtration is required. The round gauge on this model reads in psi; MPa and bar scales can be ordered. Thread is NPT; PT is the AirTAC standard and G (BSPP) is a catalogue option. Flow is published as curves, not a single rating, so send us your air demand and we will confirm sizing against the application before you order.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR series as curves rather than a single rated figure, so we do not quote a number here. Send us your line pressure and air demand and we will confirm the datasheet curve and sizing for this 1 in NPT, size-600 unit on request.
The L code marks the low-pressure regulator variant, intended for circuits working at reduced settings rather than full line pressure. The exact adjustment band for this variant is not published in the standard table, so we confirm it from the datasheet on request. Maximum inlet pressure is 1.0 MPa (145 psi), the round gauge reads in psi, and the unit operates from -5 to 70 C (non-freezing).
